I know the cows were for guild medals but not sure why it died ..
One of 2 reasons I suspect :-
1. Forgotten about.
2. Insufficient programmer time (this excuse is wearing very thin now - take someone off eldevin or something - THIS game is your revenue stream at the moment after all). It's still on the massive list, along with all the other stuff they've declared an interest in but gotten no further with.
We've not forgotten about guild medals. We've been focusing on fixing bugs at the moment, hence the long list of bug fixes in yesterday's update
9 months later... Will guild medals see the light of day? Also on topic I have no issue with guild medals not being retroactive. The top guilds are still going to get the medals that's why they're the top guilds >.<
